I have just installed Windows Virtual PC along with Windows XP Mode Beta (aka XPM) on Windows 7 RC x64 and I am absolutely amazed with its simplicity and easy to use nature. It couldn't have been made any simpler! XPM is basically built as a side feature of Windows Virtual PC – the next version of Microsoft’s client virtualization technology and comes with a free fully licensed and pre-configured copy of Windows XP Service Pack 3 (SP3).
